I had 205/60/15 US tyres on my 911 before. (I don't know why the Americans on all 911 we imported like this wrong size). Even the ratio is wrong.
Back to the Dunlop. A predecessor of the Bluresponse was N rated which means it was a certificated 911 tyre by Porsche. This is not unimportand because a 911 is very sensitive regarding quality and stability of tyres at the back. It has to carry the whole engine weight under dynamic conditions.
In the past 195/65/15 was a rare sportscar size. The positive was, most were a good choice.
Today you can get loads of different tyres of this size as it is the standard with cars like modern Golfs etc. But most of those brands with this size are just made to carry front wheel drive hatch backs.
I have a very good feel with the Bluresponse mounted on the 911 and I'm confident it would be a good choice for a Plus 4 as well.
Today Porsche only recommends Pirelli 6000 for classic cars. This is not acceptable because this tyre is way too expensive. The company just don't want to invest time and money to test successors of what they used in the past.

Ok I managed to grab 30 mins on the rolling road yeaterday so time for an update on the original thread:
2014 Morgan 4/4 Sigma 1.6 engine..modifications home made cool air induction system into standard air box with KN filter + sports silencer.
Pre-remap Results
achieved 114 bhp 98lb/ft engine rev limiter 6450 rpm
The technician commented on how the power delivery +rise was progreesive right up to rev limiter
Post -remap Results
achieved 130.4 bhp 118lb/ft engine rev limiter 7250 rpm
The surprise to me having had other cars remapped is you can really feel the torque increase in the Morgan because it is a light car.
This now is a light agile proper sports car.
So a worthwhile cost effective gain without getting into the engine.
As I said before the change highlighted the shortcomings of the Conti tyres +further improvements will be made on the suspension.
Thanks to Cain (Power to the Wolf !!) for all advise and good work..he has other mods on trial for the Sigma ..watch this space
I will be picking up some brake reaction bars from Cain next Saturday and will be discussing Panhard rod fitment.
Ok signing off now for a blast up the Yorkshire coast to frighten the natives !!!!

Wow thats an impressive HP gain for such comparatively low cost!
Well done - enjoy your "blast"!!

Wow! Kev that is impressive at a 10% gain. Well done Cain too. Interested to hear of Cain's future developments too.
When I've got some spare cash I think there will be a shopping list & a trip to Cambridge...

I'd like to see the power graphs from the rolling road...  Always interesting to see how the torque curve has changed.

Thank you! I can say that 'Wolf Cafe racer' sits at 136.9bhp @ 6610RPM Max Torque is 160.2 Nm @ 4265. with a dirty air filter! This is up by 6BHP since Johns ride up Prescott Hill (New plugs and leads) We have a stock Manifold but hi flowing side exit exhaust, Wolf Performance cold air intake that at the moment runs into the Stock AIR box with a K&N replacement air Filter, Magnecor race leads and NGK iridium plugs . Although I am happy with the Dyno results I think there would be an increase in both torque and BHP on the road due to the forced cold air induction as it's position is a full positive air point at the front of the Morgan just behind the grill (bottom). I'm working on replacing the stock air box to full Cold air induction unit and my own Manifold, and expect to reach 140BHP+  If you want to drive faster the best performance upgrade is Avon CR6ZZ's! For Handling defiantly Panhard followed by Break reaction bars. After that If you want better handling its front springs Old school with a choice of Weights (Mulfab) and AVO's. The Rear Once you have more power, Tramp bars, no sagging like springs over time just replace the rubbers when their worn. Simple is best.

What's the impact of changing from the standard plugs & leads - does that give a stronger and/or more sustained spark?

Hi Roger
She pulls better and I had an increase of 6BHP. Which I would have thought is due to a stronger spark delivered to the plugs and better plugs.
Some stuff Ive done failed as it took things out side the perimeters of the stock ECU so I shelved them for later trick wizardry!
I also use good oil Gulf Racing 5/30w to help her rev and keep everything safe 71,000 miles and thrash her at every chance.
It's not just all down to one thing it's lots of small changes like the Oil (less friction), good plugs, leads and Coil pack all need to work as good as possible for the extra bit.
